To all whom it may concern.'

Be it known that we, GUsTAvn M. GonnsMr'rH and CARL P. BAn'rELs,citizens of the United States, residing at Hamilton, Butler County,Ohio, have invented certain new and useful Improvements in LockingDevices, of which the following is a specification.

The present invention relates to locking devices and more particularlyrelates' to a lock which is particularly well suited for application tosafety deposit boxes, although the lock is in no wise limited in itsapplication to lock boxes and is suited for broad application. Manylocks are so arranged and so mounted that it is possible to strip themfrom the door or other member upon which they are mounted by poundinginwardly upon the key tube from the outside, and when the lock is soremoved, its bolt will, in consequence, be removed from its lockingposition in its socket, and the door may then be opened without furtherinterference from the bolt or lock. It is one of the objects of ourinvention to provide a lock having one or more bolts so arranged thatwhen the main part of thelock. is stripped from the door or otherelement upon which it is mounted, so as to fall therefrom, the bolt barsor parts thereof 'will nevertheless be maintained in locking position intheir sockets and will prevent the door from being opened. In otherwords, our invention comprises the provision of a lock so constructedand arranged that when mounted ina boX and locked access may not be hadto the interior of a box as a result of stripping thev mainA portionofthe lock therefrom. A further object of our invention is to provide abolt so arranged and constructed thatV when the main part of the lock isstripped from the door vor other element uponl which it is mounted,the-bolt or a part thereof will not only be maintained in lockingposition in its sockets, but will also move automatically into aposition which makes it `diflicult to tamper with the bolt by means of aWire or instrument inserted through the hole provided in Jtthe door forthe key seat of the lock. Other objects will be in part obvious and inpart pointed out hereinafter.

In accordance with our invention we provide a lock having a slidablebolt. The'bolt is normally adapted to be slid into or out of lockingposition in the usual manner by operating a key, but differs from theusual one-piece bolt construction in that the bar consists of twopieces, arranged end to end,

and is so connected that normally the bolt may be slid back and forth byoperating the key, but, when the main part of the llock is movedinwardly of a door or other element on which it is mounted, the twoparts v of the bolt will separate, and the outer part of the bolt whichis in its socket will remain therein and still function and keep thedesired elements locked together. The outer portion of the bolt ispreferably provided with a slot through which is mounted a bolt or screwengaging the door or other element on which the lock is mounted, thescrew having'a head larger than the width of the slot,

thus permitting the desired sliding move-.

ment of the bolt into locked or unlocked position and also cooperatingto maintain the bolt in locking position should the main part of thelock be removed. 'The connection between the two parts of the bolt maycomprise a pin carried at one end on one of the parts at one end andadapted to engage with-fy in a perforation in the other part at its adjacent end. These abutting ends may be properly rabbeted The outer end ofthe bolt, when the main part of the lock is removed, may be arranged toswing about the bolt or screw extending through the slot therein so asto engage suitable stops, which will aid in maintaining that part of thebolt in locking position. The said construction is disclosed and claimedbroadlyand specifically in an application filed by me June 30, 1921,Serial Number 481,474, of which this application is a division intendedto cover an alternate specific construction wherein the bolt part isprovided with a projection lor lug which is adapted to become seated inthe socket whenV this part swings about the screw as a result of theseverance of the two bolt parts. Obviously, our invention may be appliedto many types oflocks and may be adapted to many uses. Y

In order that a clearer understanding of our invention may be had,attention is h ereby directed to the accompanying drawlngs illustratingcertain embodiments ont our invention.V Referring to the drawings, Fig.1 is a horizontal section of a lock box embodying our invention and Fig.2 is a vertical section of a lock box taken on line 2-2 of Fig. 1.Similar reference characters designate similar parts throughout theseveral views oi the drawings.

In the drawings we have illustrated our improved lock as being mountedon the outer face of a drawer in a safety deposit box. The constructionof the box is similar to the construction disclosed and claimed in ourapplication tor improvements in lock box, Serial llumber472,501, tiledMay 25, 1921. In said application we have described, and in the drawingssubmitted herewith we have illustrated, a safety deposit lock box whichcomprises top wall 1, bottom wall 2, side walls 3 and 4 respectively,door 5, hinged in the usual manner, as at 3, to one side 3 of the box,and a lock 7 secured to the rear of the door by means ot bolts 8. Thekey tubes of the lock are shown at 10 and an abutment plate 13 which isshown to comprise the front tace et a drawer in the box is shown securedto the side walls 14 and 15, and to the bottom 16 ot the drawer byspotwelding or other suitable means. To the inside wall 3 ot the box islirmly secured a plate 20 having a rigid shoulder portion 21 adapted toabut against the rear tace of plate 13 along its edge which is near side3 of the box. Rigid member 22, similar to member 20, is securedinteriorly oiI the wall 4 of the box, and has a similar shoulder orabutment 23 adapted to abut against the rear 'tace of plate 13 along itsedge which is near the wall 4. l/Vhen it is attempted to strip the lock7 away from the door 5 by pounding upon or by applying pressure to thekey tubes 10, the lock 7 will be forced against the rigid plate 13 whichin turn is held against inward movement by the shoulders 21 and 23 ofthe side pieces 2O and 22, thusy preventing the lock 7 from beingstripped from the door 5 in consequence of the poundingl In theconstruction so far described, when the' door oit the box is opened inthe regular manner, the drawer therein is free to be pulled out. A lock24, which embodies our present invention, is shown to be mounted on therear tace of the plate 13 and is adapted to lock the drawer in the box,so that even after the door of the box has been opened in the regularmanner, the lock which is mounted on the drawer must be operated in theregular manner before the drawer may be pulled out. Lock 24, except forits bolt, may be of any one of several usual types which slide the bolt,and may be secured to the inside of the plate 13 in any usual manner, asby means of screws 25, with its key tube 26 extending through aperforation in the plate 13. As shown, the lock 24 is of the typewherein one key operates two oppositely disposed bolts simultaneously toslide the same into and out oi' locking position. instead oit each ofthese bolts being in one piece, as is usual, each bolt consists of twoparts, 27 and 28 respectively, placed end to end, and sever-ablyconnected, as by means et a pin 3() on one ot these pieces, such aspiece 27, which pin is movably seated in a perforation 31 in theabutting piece 28. li desired pin 30 and perforation 31 may be providedon end portions which are reduced as at 2f). The outer severed piece 28oi each bolt is provided with a slot 32 and a screw or bolt 33 isfastened on the plate 13 so as to extend through this slot 32, the screw33 having a head wider than the width ot slot So long as the two piecesot the bolts are connected together, their outer portions 3'? are movedby the ordinary operation t the key into and out ot lockingv position,one piece 28 moving into and out of locking engagement behind theshoulder 21 ot piece 2O and the oppositely disposed bolt piece 28 movingits portion 37 into and out of locking engagement behind the shoulder 23ot the piece 22. rIhe rabbeted portions 29 of the two pieces 27 and 28of each bolt bar, and the pin connection therebetween, is such that whenthe main part of the lock 24, including bolt sections 27, are movedinwardly of the plate 13, the outer pieces 28 or' the bolts will remainvmounted on plate 13, beL ing held there by screws 33. The portion ofeach oit the pieces 28 which is inwardly of the screw 33 is heavier thanthe portion on the other side of screw 33, and when it is treed frombolt section 27, piece 28 will pivot about the bolt 33. Each bolt part28 has a projection or lug 38 which will become seated behind theshoulders 21 and 23y whenever these outer bolt portions 28 have turnedabout the pivots 33, as when the lock has been removed from the door andportions 28 are free of portions 27. In Fig. 2 the dotted lines indicatethe second position of the projection 38 and the outer portion 28 of abolt bar.

It will be apparent that the lockand bolting means described are suchthat the box or drawer or other element which is locked thereby may notbe opened even though the main part of the lock is stripped from itsmounting, and that the portions 28 of the bolts may be so arranged anddesigned that whenever the main part of the lock is displaced they willautomatically move away from the key tube perforation in plate 13 andinto a position where they may not be easily reached Vor tampered withto eiect their adjustment into unlocking position. The lock disclosed isnot limited to use in connection with safety deposit lock boxes but maybe adapted to many different uses.

Also, instead of arranging the bolts to abut behind shoulder members 2land 23 separate sockets may be supplied for the bolts.
